BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 251,922, dated January3, 18 82. Application filed June 23, 188i. (ModeL) To all whom it mayconcern:

Be it known that I, STEPHEN S. NEWTON, a citizen of the United States,residing at Binghamton, in the county of. Broome and State of New York,have invented certain new and useful Improvements in Bottle-Stoppers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure 1 is a vertical section of a stopper containing my invention.Figs. 2, 3, and 4 are vertical sections of modifications of parts of theinvention. Fig. 5 is a plan view, partly in section, of Fig. 2. Fig. 6is asimilar view of Fig. 3; and Figs. 7 and 8 are detached views, inperspective, of the stopper shown in Fig. 4.

In all of the figures, A is the cork-tube sec tion, having a flange, B,adapted to cover the cork D and mouth of the bottle.

E is a screw-threaded tube-section engaging with threads on thecork-tube and rising and falling thereon, and provided with avalve, U,which, when screwed down, closes an opening,

a, in said cork-tube, to prevent liquid being discharged through tip 6.

e is a spurprojecting horizontally from tubesection E and engaging witha stop, of, to limit the rotation of said tube when itis beingscreweduponcork-tubeA. InFig.1thisst0pa-"isformed on the upper end of thecork-tube A, a portion of which is cutaway, as indicated at a of. InFigs. 2, 3, 5, 6 the stop projects upwardly from flange B in the path ofspur 0, while in Figs. 4 and 8, b is a spiral groove or slot in flangeB, the wall at the end of which forms said stop a In practice I prefer agroove upon the inner face of flange B, the upper edge of the flangebeing bent outwardly a little to facilitate entering spur a into thegroove b, and afterward closed in to retain the spur.

In Fig. 1 the opening a is formed in the flange or plate which separatesthe lower part ot'co'rktube from its upper enlarged part, and the valve0 consists of the flat lower end of the tube-section E, which is closedat this point, except that it has one or more eccentric ports, 0.

a is a packing-washer, against which the valve 0' abuts when it isscrewed down. In Fig. 2 the valve 0 is attached to the lower end oftube-section E, and is by preference conical in form, the inner surfaceof the lower end of the cork-tube being correspondingly shaped. In Figs.3 and 4. the valve 0 is arranged within the tube-section, and near itsupper end, leaving ports or glands on two or more sides, and engageswith the upper end of the cork-tube.

c. is a thumb-plate having a milled edge, by which to rotate thetube-section E and screw it up or down.

It will of course be understood that the function of the spur e and stopa is to limit the retation of tube-section E when being rotated in thedirection necessary to raise the valve from the opening a, the rotationin the opposite direction continuing until the opening a has beenclosed.

Of course the washer a. might be dispensed with and the lower fiatend ofthe tube-section in Fig. 1 made to close the opening a; but I prefer theconstruction shown.

I have shown in my Patent No. 186,364, for oilers, dated January 16,1877, a construction of valve-seat, rising and falling valve attached toscrew-threaded discharge-tube, and stops which limit the rotation of thetube, which in somerespects resemble the construction shown in thiscase; but the invention shown in that patent would not be desirable asapplied to the bottle'stopper in this case, because it would necessitaterecessin g or cutting away the outer edge of flange B to form the stop,and would consequently necessitate extending the spur e'horizontallyacross the upperface ot'saidflange, and-then bending itdownward to engage with the stop, which it would be impracticable to do.This difticulty I avoid in my present construction'by supporting thestop above the plane of flange B, and in close proximity to the rotatingdischargetube, and then projecting the spur horizontally from thedischarge-tube, so that the plane in which it rotates shall beintersected by the upwardly-projecting stop. By this construction andarrangement of parts I am also enabled to hide both the spur and thestop from view, as shown in Fig. 4.

What I claim is-. '1. In a bottle-stopper, the combination of ascrew-threaded tube-section attached to the flange B, and provided witha valve-seat, a screw-threaded tube-section engaging there with andprovided with avalve and with a hori- 5 zontally-projecting spur, and astop supported above the flange B and in the lateral path of the spur,substantially as set forth.

2. In a bottle-stopper, the combination of a screw-threaded tube-sectionattached to the flange B, and projecting both above and below saidflange and provided with a valve-seat, a screw-threaded tube-sectionengaging therewith and provided with a valve and with ahorizontally-projecting spur, and a stop formed on theupwardly-projecting flange which is at- "tached to said flange B, and inthe lateral path of the'spur, substantially as set forth.

3. In a bottle-stopper, the combination of a screw-threaded tube-sectionattached to the flange B, that portion which projects above the flangebeingscrcw-t-hreaded internally and provided with a valve-seat, anexternally screwthreaded tube-section engaging therewith and providedwith a valve and with a horizontallyprojecting spur, and a stop formedon the upper end of the cork-tube and in the lateral path of the spur,substantially as set forth.

4. The combination, in a bottle-stoppeiyof the internally screw-threadedtube-section projecting above the flange B, and having a centralopening, a, with the externally screwthreaded tube-section E, closed atits lower end, and having one or more eccentric ports, 0, substantiallyas set forth.

In testimony whereof I aflfix my signature in presence of two witnesses.
